A phone tester is someone who tests phone features and applications for different phone or product testing companies. Testing may be done to improve features before public release, or after release, in exchange for a review. A phone tester might evaluate aspects like user friendliness, battery life, digital camera capability and global positioning systems (GPS) just to name a few. Phone testing will probably not earn you a living. In some cases there is small compensation. More often you get to keep the product you test or receive some small reward like a gift card.
